Scanned the car today, and it only ran 3-4* KR. I don't think that is too bad for no other mods, this is even on the stock spark plugs. But I did convince him to do a U-bend delete and a 3" DP. I realize that 4* is worse than 0*, but it is not as high as I was expecting.
3-4 * of KR with 3.5?
Yes, sir. That is correct.
im assuming u did some WOT runs? wait til summertime lol
Get headers.
Car will knock more when it is cold. :th_thumbsup-wink:Quote:

It was pretty warm out today. ~45 *F
headers = more gas mileage
there are guys with cam,headers ect. getting 30mpg on the highway. The tune is key.
I'll let him know! HAHA, he'll never do it. He put the headers in my GTP and nothing fit right. Plus he doesn't have alot of money just sitting around to spend. Oh, and another thing is he wants it to be more of a sleeper, so not that loud.
Will the spark plugs lower KR then? Since he hasn't done them yet, he wants to know what to expect.
Mine was barely louder than stock with headers.
the resontator and the mufflers determine the sound level.
And another thing I was wondering about was the spark plug gap. .050 right?
higher, i think .055? stock is 0.060
I just go with .055
Just clarifying. Not saying you guys are wrong, but I read somewhere else on this forum that if you are running between 6 and 12 lbs of boost to run a .050 gap. he is peaking at ~11.5lbs
11.5 im only 2 pounds higher? his must be bad boost cuz of restrictions?
I ran 13 psi on a .055 gap with no blow out.Quote:
